ABSTRACT
Corpus callsoum (CC) is the largest commissural fiber connecting the cerebral hemispheres. The gender difference in the size or the shape of CC is a long standing dispute. Some reported that adult female CC had more bulbous splenium and larger area considering brain size, but others failed to replicate this findings. There is no definite consensus on sexual dimorphism of CC yet, although extensive studies on sexual dimorphism has been expected to provide a clue to explain sociopsychological differences between male and female. This variable results are attributed to limited number of subjects, measured parameters, and method of measurement. We have employed comprehensive analytic parameters with large subjects to understand gender differences on CC of healthy Korean adults. We have analyzed the magnetic resonance image (MRI) in adults free from neurological disorders. The subjects were composed of 108 young people (3rd decade; male 51, female 57). Total area, its 5 sub-areas, linear parameters including height, length, and width and five specific angles of the CC were measured on the midsagittal MR images with NIH Image program (R) (Ver 1.6). The gender differences were observed in the area of splenium and length in the group. The male CC have larger splenium and longer length than female. The angle between neural axis and base of corpus callosum in female was significantly larger than that of male. This study reports not only gender difference of adult CC, but Korean adult standard morphometric data of CC research. These results might serve a useful basic data for various research in the fields of neuroanatomy, neuroradiology, and neuropsychiatry.
